My daughter had 100 spoken words by her first birthday and she had never seen a TV. I realize that is somewhat unusual so I didn't take your poll (I suspect TV would not have made any difference). At 4 her speech is still pretty amazing with limited tv. She uses advanced words and concepts correctly. Her world is expanding though, and it isn't just me and the TV anymore.

Incidentally, my son is 15 months old and MAY have said his first word yesterday, "key." He may also have just been clearing his throat.
